Abstract

A fuel tank (1) possesses, for the introduction of fuel, a filler pipe (5) which is led through an orifice (6) of the fuel tank (1) with all-round clearance. The orifice (6) is sealingly closed by means of a sleeve (4) bearing against the fuel tank (1) and against the filler pipe (5). The orifice (6) can thereby be made relatively large, so that it can be additionally used also as a service or assembly orifice after the sleeve (4) has been removed. The number of orifices necessary on the fuel tank (1) can be reduced as a result, so that both the maximum filling quantity and the permeation tightness can be increased.

In addition, in the known Fuel Tank of prior art, the special moulding meeting of the fuel-tank wall that the aperture is required produces adverse influence, and it has reduced the maximum volume that may feed in raw material.Will reach when the predetermined installing space that is provided under the prerequisite of maximum feeding quantity, each hole in the Fuel Tank all means undesirable restriction.
In addition, the hole of offering for the installation petrolift is arranged on the scope of back row's seat usually, thereby can only touch from inner chamber.Therefore, maintenance of Fuel Tank in-to-in or repairing work are also relevant with the danger of health except foreign odor, for example because the benzene that discharges and other material.
The objective of the invention is to, propose a kind of Fuel Tank of the above-mentioned type, case is produced in this combustion does not need other installation or service hatch except essential hole especially charging aperture.The special type of wherein especially having cancelled the fuel-tank wall that can reduce volume becomes and only can be from the hole that automotive interior touches.
According to the present invention, this purpose is achieved in that to be that charge pipe inserts in the Fuel Tank with interval with respect to opening, charge pipe by means of seal ring and Fuel Tank detachable be connected hermetically.For this reason, the function of keeping in repair or repairing has been finished in the hole that is used for fueling simultaneously.For this reason, this hole has sizable diameter, and wherein this hole is closed hermetically by means of seal ring when running state.Touch the inside of Fuel Tank if desired, seal ring and charge pipe can unload from Fuel Tank, thereby can touch inner chamber without a doubt.Therefore, can reduce the number in the required hole of Fuel Tank according to the present invention.In addition, by charge pipe being advantageously provided rear side scope, can preferably touch from the outside by gear case at automobile.Thereby can avoid the smell in the inner chamber.
Seal ring can be installed in the surface of Fuel Tank basically flatly, and links to each other with Fuel Tank.Especially simply the joint that is seal ring is arranged on the Fuel Tank in an embodiment of the present invention, and wherein Fuel Tank has an adapter and seal ring is installed in this adapter.Thereby seal ring can link to each other with adapter and sealing easily with a wet finger.Thereby produced easy leak free joint owing to seal ring and adapter are tangent, this joint has high mechanical admissible load simultaneously.
In an especially favourable improvement structure of the present invention, seal ring is designed to taper, and its big hole surrounds adapter.Like this, seal ring can compensate the dimensional discrepancy that occurs when in automobile Fuel Tank and charge pipe being installed.When seal ring was arranged to respect to charge pipe because of carelessness, seal ring also can surround adapter hermetically.Can also further improve simultaneously the mechanical stability of seal ring.
In especially favourable embodiments of the invention, seal ring and charge pipe fuse.The sealing between seal ring and charge pipe of having saved for this reason otherwise having needed.Thereby further improved staunching piece, reduced the number of part simultaneously, thereby except reducing weight, also reduced manufacturing cost.
In order to take off seal ring, at first the charge pipe at both ends that will link to each other with vehicle body usually unclamps from its bearing.Then from the hole, take out charge pipe.By contrast, in an especially simple improvement structure of the present invention, seal ring has a compliant section, thereby does not need to remove charge pipe, and at first can pull down all the other fasteners of charge pipe.Exactly, the compliant section that only needs for example to be provided with bellows unclamps at its end towards Fuel Tank.Simultaneously, the design-calculated seal ring makes and installs obviously easily like this, because the inexactness in assembling has been done compensation by this compliant section.
In another especially favourable improvement structure of the present invention, seal ring links to each other with Fuel Tank by means of quick coupling.Therefore can also need not speciality tool without a doubt and just can unclamp connection between seal ring and the Fuel Tank, thereby also can reduce the required time of corresponding repairing work.
In an especially favourable improvement structure of the present invention, above-mentioned joint has a bayonet fittings.Also can operate the mistake when wherein having avoided to a great extent installing without instrument for this reason.
In another especially favourable improvement structure of the present invention, charge pipe has a boiler check valve.Like this, even the fuel in the Fuel Tank can not pass back in the charge pipe under extreme driving conditions yet.In addition, boiler check valve has stoped the unexpected overflow of Fuel Tank when reinforced.
The present invention allows different embodiment.In order to illustrate that groundwork of the present invention has been described in the drawings one of them embodiment and explanation below.Wherein:
